T0 all w/ltomtmay concern:

Be 1t known that I, ALBERT H. DnNNrs'roN,

a `citizen 'of the United States, residing at Ferguslalls, in the county of Ottertail and State of Minnesota,have invented certainnew `and useful Improvements in Concrete-Wall Forms; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as willV enableothers skilled in the artto which it appertains to make and use the sarne.v

My invention has for its object to provide an improved wall form adapted for use in .constructing monolithic or slushed-in concrete walls, and n to such ends, generally stated, the invention consists of the novel devices `and combinations of deviceshereinafter described and defined in the claims.

This wall form :may be used for constructing walls of various differentkinds of buildings, but is primarily designed and particularly adapted for use in building the con-` crete walls` of barns, bins and likebuildings that are capable of being erected `onthe unit plan, `s0 that standard wall plates and the like may be employed.V

In the accompanying drawings, which `illustrate the invention, like characters indicate` like parts throughout the several views. n "Referring to the drawings:

Figure 1 is a `fragmentary side elevation, with some parts broken away, illustrating the improvedwall form; n n

Fig. 2 is aplan view of the wall,` form shown in Fig. 1; and

Fig. 3 is a vertical section taken on the Ilines 3-f3 of Figs, 1 and 2.

The inner side of the form islmadeup of a n, plurality of flat plates 4, preferably of sheet ,metah reinforced at the horizontal edges by angle strips 5, Said plates i, at the corners 4of the structure, are rigidly but detachably secured tovertical angle bars 6, by nutequipped bolts 7 that perform `the `functions presently to `be noted;

i. In the Wall structnre, at poi ts where intermediate corners are to be formed, the ends of the plates l are abutted together at 8 and,

oneach side `of these abutting ends, verti` cally GXtended angle bars `9 are rigidly secured. u l The outer side of the wall form is made-.np of apluralityof plates 10, preferably of sheet metal, reinforced at their horizontal edges by angle barsll riveted or otherwise rigidly secured thereto. These plates 10, at the corners of the building and at places where intermediate columns are to be formed, are spaced apart, respectively, at 12 and 13.

To form the corner columns, approximately rectangular so-called corner column plates 14 are applied. Said plates lei, at their inner edges, have flanges through which the nut-equipped bolts 7 are passed so that the latter'not only clamp said plates lll to the outside wall plates 10 but properly space the inside and outside wall plates. At their outer edges, said plates 14C have outstanding flanges rigidly but detachably connected by short nut-equipped bolts 15.

For forming the intermediate wall columns at the gaps 13,1 provide approximately U-shaped so-called intermediate column plates 16 having edge flanges that overlap the ends of the plates 10. Nut equipped bolts 17 passed through theedge flanges of the column plates 16, through the ends oi the outside wall plates 10 and through the inside wall plates l and angle bars 9, serve to space theinside and outside plates and to securely hold said column plates 16 in position to form the intermediate wall columns.

The outstanding flanges of the angle bars 9 afford means to which plates, not shown, may be V,bolted or otherwise secured when partitions are required in the building being erected. `The column plates 14: and 16 not only form the wall columns where required,

but they very greatly stiifen the entire form plan so that the building may be increased or decreased in units representing distances between columns, while using the saine wall plates. The .valls will usually be designed of a standard height, but, of course, the form can be varied as to height and, moreover, the

" wall plates may be of any desired horizon `tal length so as to vary the unit used in erection of the building.

Preferably, the horizontal reinforcing angles applied to the inside and outside wall plates will be applied substantially as shown in Fig. `8, where it will be noted that the uppermost angle -is flush with the topmof the `upper wallplate While the lower or interso t'ar as this invention is concerned. Certainy oiff'tlie reintorcementsimay be supported tem`` Vporarily by the bolts 7 and 1 7. These bolts,

after theconcrete has set so to support its own weiglit'and maintain a set form, will be driven out and the bolt holes therea'lter filled with cement. VIn Fig'. 2, the numeral 18 indicates verticalfrods for reinforcing the cor- 'nercolumns, andthe numeral 19 indicates Vertical rods for reinforcing the intermediate columns. rI`his torni' is especially designed to be made entirely from metal and, being thus constructed, will last for a very' long timev and there will be no waste of material used in the form. vAs is a well known tact, Wooden forms are, in the long' run, very eX- pensive because ot the waste in lumber incident tobuilding up and tearing down.

VWhat I claim is: j

1. A form for making concrete walls comprising inside and outside wall plates, one ot said classes of plates'being'spaced at corners and at intermediate columns, corner column forming plates connected to said spaced plates at the corners of the wall structure', and bulged intermediate column plates connected to the spaced intermediate ends of said plates and positioned to form intermediate columns.

' 2. A form for making concrete walls comprising inside and outside wall plates, said outside plates being spaced at corners. and at intermediate columns, angular corner column plates connecting said outside plates at the corners ofthe wall structure, and outwardly bulgedintermediate columnv plates connecting the spaced'intermediate ends of said outside plates.

3. A form tor making concrete walls comprising inside and outsideV wall plates,rsaid inside plates beingv connected in continuous arrangement,- said outside plates being spaced at corners'v and ,at` intermediate columns, angular cornercolumn plates connecting said outsideplates in thecorners of the wall structure, andoutwardly bulged intermediate column plates connecting the spaced intermediate ends of said outside wall platesfV v f 4f.- Aform for making concrete walls comprising inside and outside wall plates, said inside plates beingl connected in continuous arrangement, said outside plates being spaced Vat corners Y' and at intermediatev columns,

angular corner column `plates connecting` said'outside plates in the corners of the wall structure, outwardly bulged, intermediate column plates connecting the spaced intermediate ends of said outside wall plates, and removable bolts connecting said inside and outside plates and column forming plates.V

5. A form for making concrete walls comprising inside and outside wall plates, said inside plates being connected in continuous arrangement, a Vertical angle bar to which the adjacent ends of said inside plates are secured at the corner of the structure, flanged .bars secured to said inside plates adjacent to buton opposite sides of their intermediate abutting ends, said outside wall plates being spaced at corners and at intermediate columns, separable angular corner column plates detachably secured to said outside plates, and outwardly bulged intermediate eolunni plates detachably connectin the ends of said outside wall plates at intermediate columns. p 6. A form for making concrete walls comprising inside and outside wall plates, said inside plates being connected in continuous arrangement, a vertical angle bar to which the adjacent ends of said inside plates are secured at the corner of the structure, flanged bars secured to said inside plates adjacentto but on opposite sides of their intermediate abutting ends, said outside wall plates being spaced at corners and at intermediate columns, separable angular corner column plates detachably secured to said outside plates, outwardly bulged intermediate column plates dctachably connecting the ends of said outside wall plates at intermediate columns, removable bolts extended through flanges of vsaid intermediate column plates, through said outside wall plates and through said inside wall plates and the ianged bars at adjacent intermediate joints, and other removable bolts passed through flanges of said corner column plates, through said outside wall plates, inside wall plates and corner angles.

7. A forni for making concrete walls comprising inside and outside wall plates, said inside plates being connected in continuous arrangement, a Vertical angle bar to which the adjacent ends of said inside plates are signature.
